If a believer were to know the punishment (in Hell) none would have the audacity to aspire for Paradise (but he would earnestly desire to be rescued from Hell), and if a non-believer were to know what is there with Allah as a mercy. none would have been disappointed in regard to Paradise.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لَوْ يَعْلَمُ الْمُؤْمِنُ مَا عِنْدَ اللَّهِ مِنَ الْعُقُوبَةِ مَا طَمِعَ بِجَنَّتِهِ أَحَدٌ وَلَوْ يَعْلَمُ الْكَافِرُ مَا عِنْدَ اللَّهِ مِنَ الرَّحْمَةِ مَا قَنِطَ مِنْ جَنَّتِهِ أَحَدٌ  

Messenger of Allah ﷺ said, When the funeral is ready and the men carry it on their shoulders, if the deceased was righteous it will say, 'Present me (hurriedly),' and if he was not righteous, it will say, 'Woe to it (me)! Where are they taking it (me)?' Its voice is heard by everything except man and if he heard it he would fall unconscious."  

أَنَّهُ سَمِعَ أَبَا سَعِيدٍ الْخُدْرِيَّ ؓ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا وُضِعَتِ الْجِنَازَةُ وَاحْتَمَلَهَا الرِّجَالُ عَلَى أَعْنَاقِهِمْ فَإِنْ كَانَتْ صَالِحَةً قَالَتْ قَدِّمُونِي وَإِنْ كَانَتْ غَيْرَ صَالِحَةٍ قَالَتْ يَا وَيْلَهَا أَيْنَ يَذْهَبُونَ بِهَا يَسْمَعُ صَوْتَهَا كُلُّ شَىْءٍ إِلاَّ الإِنْسَانَ وَلَوْ سَمِعَهُ صَعِقَ  

The Prophet ﷺ said, "When a funeral is ready and the men carry the deceased on their necks (shoulders), if it was pious then it will say, 'Present me quickly', and if it was not pious, then it will say, 'Woe to it (me), where are they taking it (me)?' And its voice is heard by everything except mankind and if he heard it he would fall unconscious."  

أَنَّهُ سَمِعَ أَبَا سَعِيدٍ الْخُدْرِيَّ ؓ قَالَ كَانَ النَّبِيُّ ﷺ يَقُولُ إِذَا وُضِعَتِ الْجِنَازَةُ فَاحْتَمَلَهَا الرِّجَالُ عَلَى أَعْنَاقِهِمْ فَإِنْ كَانَتْ صَالِحَةً قَالَتْ قَدِّمُونِي وَإِنْ كَانَتْ غَيْرَ صَالِحَةٍ قَالَتْ لأَهْلِهَا يَا وَيْلَهَا أَيْنَ يَذْهَبُونَ بِهَا يَسْمَعُ صَوْتَهَا كُلُّ شَىْءٍ إِلاَّ الإِنْسَانَ وَلَوْ سَمِعَ الإِنْسَانُ لَصَعِقَ  

Messenger of Allah ﷺ said, "When the funeral is ready (for its burial) and the people lift it on their shoulders, then if the deceased is a righteous person he says, 'Take me ahead,' and if he is not a righteous one then he says, 'Woe to it (me)! Where are you taking it (me)?' And his voice is audible to everything except human beings; and if they heard it they would fall down unconscious . "
